Description
Miharu Mitsuka is the 36-year-old widow mother of protagonist Soji Mitsuka. She runs her own café, Adolescenza. Miharu bears such a strong physical resemblance to her child that they could easily be mistaken for siblings. She has shoulder-length auburn hair, red eyes, stands approximately 161 centimeters tall, and weighs around 49 kilograms.

Miharu is fully aware of her child's bigender identity, supporting the dual expressions of male presentation at school and home, and female presentation as both the civilian identity Solar and the transformed hero TailRed during battles against extradimensional threats. This knowledge comes partly from the underground command center beneath their home and café, built by the interdimensional visitor Twoearle. Miharu actively assists operations there, though she cannot use the Tail Gear transformation technology herself due to age restrictions.

Her motivation for supporting the twin tail warriors connects to her own unrealized youthful aspirations to become a heroine. Miharu openly expresses pride in her child's role as TailRed and provides logistical support during confrontations with Elemelians. She accepts Twoearle's romantic advances toward Soji/Solar, even encouraging Twoearle to "make her offspring a hero/heroine" and facilitate maturation. Miharu treats Aika Tsube with maternal affection comparable to a daughter, though she remains unaware of Aika's deeper romantic feelings toward Soji/Solar.

Personality assessments note Miharu retains chūnibyō tendencies from her youth, characterized by persistent delusions of grandeur or heroic fantasies. She prioritizes maintaining domestic harmony and accommodating individuals frequenting her home or café, leading to an unexpectedly cooperative relationship with Twoearle despite their differing origins.

Her operational contributions include managing the command center during missions and providing sanctuary for the twin tail warriors. Miharu exhibits no concern regarding her child's gender fluidity, focusing instead on enabling the protection of Earth from interdimensional threats. Her role remains consistently supportive, fulfilling both parental responsibilities and auxiliary functions for the twin tail warrior team.
